Is there a node that allows you to export a view as a dxf?
I never tried it but if you speak python you could look here to write your own:
Also check this post for analogy
If you download the package Chynamo, there is a node View.ExportDWG with a Python script within it; that Python script could be modified easily using the second API reference @GregX provided you… looks like you would only really need to change 2 lines for it to export DXF
Here is the code within that node, I still recommend downloading that package anyway (lots of useful nodes, plus you can see how the View.ExportDWG nodes inputs work):
import clr clr.AddReference("RevitNodes") import Revit clr.ImportExtensions(Revit.Elements) clr.AddReference("RevitServices") import RevitServices from RevitServices.Persistence import DocumentManager doc = DocumentManager.Instance.CurrentDBDocument clr.AddReference("RevitAPI") import Autodesk from Autodesk.Revit.DB import * import System from System.Collections.Generic import * import sys pyt_path = r'C:\Program Files (x86)\IronPython 2.7\Lib' sys.path.append(pyt_path) def _ExportDwg(xfolder, xview): options = DWGExportOptions() views = List[ElementId]() id=ElementId(xview.Id) views.Add(id) xname="Export-" + xview.Name + ".DWG" try: rtn = DOC.Export(xfolder, xname, views, options) except: rtn=None return rtn XFOLDER = IN XVIEW = IN DOC = DocumentManager.Instance.CurrentDBDocument rtn = "Export DWGs failed" if IN == True: for abc in XVIEW: try: rtn = _ExportDwg(XFOLDER, abc) rtn = "Export DWGs successful" except: rtn = "Export DWGs failed" OUT=rtn
